Hi and Welcome! I have been on aza for 2 years this month. I went on it b/c i was dependent on pred. and really wanted to get off. It took a few months and several tests to get my dosage correct. I think it took about
5-6 months to fully kick in for me. I had some nausea when I first started taking it. I was taking it in the mornings but switched to evenings and that really helped. I do have a lot of exhaustion. I can't say if that is the med or UC in general. I tend to get sick more often since I started aza (BUT I have a preschooler who is a germ machine). I have bloodwork done every 3 months just to make sure everything is okay. Otherwise no other side effects for me.
